trolley base 9. The spring .11 connected at .011e end to the-trolley pole by vmeans ofl the stirrup 11, and at theother to the boftom of the tubular casting 10, acts to hold ,t ie trolley wheel which is carried by the outer end of the pole. in under-running Contact with the trolley Wire. i Y 'The automatic locking device described in Patent No.k 684,950 to Robinson serves to hold the trolley pole in'axed horizontal position when,- the locomotive is drawing current from the condulctoreable or from a storage battery. It consists-of the two lpins 11'a1 adapted to enter sockets in the lower cross bar of the stirr'up and carried by the swinging arms l1b pivoted to the top flange, of the casting 10 and .drawn tol ward each other by the spring' 11. ln lieu f` of thisdevice or supplemental thereto,a holder 11@ may be secured to thelocomotiie 7 frame in a location to engage the outer lend of thevtrolley pole and secure it in horizontal position when desiredf Each trolley base Sis an elongated cylinf dricaly casting, yertically movablel in the guides 13 which are carried by and preferably integral with the bracket 14 bolted to the side of the locomotive.r rthe lower limit ot movement ofv the trolleybase is determined by, they shoulder 15 at its'npper end. lThe base is adjusted to itsup'per or lower position by means of the link 1G pivot-ed at one end to the trolley base and at the other yto the arm 17. This armr is pivoted to the- 'locomotive yframe at 18, and is rigid withthe 90 hand lever 19. By throwing-,the flatter through an are of approximately ninety de- A y grecs, the arm' 17 is rotated through aucorrespondingA are, and the trolley base. is moved from rone extreme position'oj adjust--y ment to the other. N A A It'will be observed that the fixed 4.pivot at one end of the arm i7 is so locatedivithiesperrt to the axis of the trolley base,and the t lengths kof thearm and linkl are so pro-ll portioned that whenihe hand lever 1917 thrown to its horizontal position the morini! pivot passes beyond":the linemjoining the 'iixedpivot 1S )viththe point at whichthe link ,16 is piroted to the base and en es the inner face oit thev guide13.,thenebv Liuto-l' y matic/ally lockingthe base, in its-upper position of adjustment.. n y U A vertically adgustable trolley baseA is lcle- .sirable under many contlitnins of operati/mi. 11.0
